There is none.

I'm in the same camp as Mr Chase on this one.

Currently I dry out the scrubber immediately aftere diving, I've got a couple of stoppers for the connectors on the scrubber unit. I use these to seal it up for the week.

In reality if I've done two dives on it over a couple of weekends, the third I'll refill... as the man says what's £7.50 in the big scheme????

Never been comfortable to leaving the unit open for any length of time although I know many people that do.

I would have gone on to use this canister for 1 20m or less dive had it not been for getting concerned over this thread.

I have emptied scrubbers after 100mins diving and after being left overnight and found a layor of hard material that breaks into lumps when emptying the can. I dont know if this is a problem in use but it just feels bad to have hard lumps or layers in the scrubber. Having fresh lime in the unit makes me feel more confident during the dive.

Hello,

This is my 3 scrubber that I am using and after I emptied the contents, the material inside was all lose as if new (new does not mean without Co2 and can be reused!!) and no lumbs in it. I used it in the 30m range so not that deep maybe as Chasey but is it normal to ahve lumps in the material?

The lumps comes from water / dampness in the scrubber. even when the sofnolime dries out it still sticks together, hence the lumps. Sofnolime disolves fairly easily in water, Spherasorb is much better in this respect.

Try leaving a ball of sperasorb and a grain of sofnolime in a glass of water by your bed overnight (make sure you don't drink it) You will find the spherasorb still there in the morning, but the sofnolime has disolved.

When you wet the lime in the canister, it partly disolves, then drys and re-forms into the lumps, the extent of the lumps depends not on the depth range, but on the volume of moisture you pass into the canister.

Hi Dave,

There is. Diffusion. Passage of a material from an area of high concentration to an area of low concentration.
Agreed in the case of CO2 it's low in comparisson to breathing but it's still there and you're potentially talking a much longer exposure. The nett effect will also be increased by the water exiting the scrubber from high to low conc.
In practice I go with the ziploc bag as well for one weekend to the other if I know I'm not pushing any of the accepted limits. Other than that - any doubts, bin it.

As here I dive in a freezing 14'c as opposed to UK temp. where maybe more condensation will form? due to colder water temp. ?

Never Never Never re-pack previously used scrubber material. It could be fatal.

Stay alive!
